摘要
A linear relationship between fracture strain, epsilon(f), and yield strength first observed by Lloyd (2003) in aluminum alloys is re-examined for age-hardenable AA6063. A breakdown in the relationship is observed if AA6063 is pre-strained prior to ageing. A linear relationship is recovered for epsilon(f) versus dislocation initial inter-obstacle spacing, l.
